I have one of those 510 thread ceramic nails with a coil in the middle with a little glass dome that slides over it. I've been using it with an ego battery for awhile and it works pretty well especially with the cannastick bubbler attachment, but I just recently put it on my iStick 30w at 7.5 watts 3.7v with the coil reading 1.8 ohms. It produced a lot more vapor but I'm afraid I might burn the coil out if I keep vaping it that high. Does anyone know the highest voltage these can take consistently without risk of blowing?
